  • How can tools like these help Ukrainians to stay connected and coordinate?

    There is Jami which works peer to peer, and SSB which is a gossip protocol.

    Especially when there is no internet connection

    But if there is no internet connection, I don’t know how you can install them in the first place.

    If you have an internet connection at the moment and a couple of laptops nearby with GNU+Linux (I know this situation is rare when a war is going on), you could use something like naxalnet (disclaimer: I made it) or read the awesome mesh for starting a mesh network.

    Also, if you use a phone, see the Guardian Project’s website which might help you.

    Basically, your chances of connecting with people in such a situation is very low, since only privileged people own multiple laptops or phones, and most privileged people might have left the country before or when the war started (correct me if I am wrong, I don’t know much about the situation)





  • That’s not what will happen. Note the version number in my reply. Ubuntu based distros won’t remove old kernels after updating to newer kernels. This is probably what’s taking space in your /boot partition.

    In the screenshot you posted, there are 5 kernels:

    • vmlinuz-5.11.0-40-generic
    • vmlinuz-5.11.0-41-generic
    • vmlinuz-5.11.0-43-generic
    • vmlinuz-5.11.0-44-generic
    • vmlinuz-5.11.0-46-generic

    But there are only three initramfs images:

    • initrd.img-5.11.0-40-generic
    • initrd.img-5.11.0-41-generic
    • initrd.img-5.11.0-43-generic

    It is likely that your boot partition doesn’t have enough space to store the initramfs image for booting kernels 5.11.0-44 and 5.11.0-46. To make enough space, you can remove the old kernels. According to your uname -a output, you are currently running kernel 5.11.0-43. And I assume you have no problem with the current kernel. If that is the case, there is no need for kernel 5.11.0-40 and 5.11.0-41.

    So, you can remove the two kernels. Old kernels are probably not removed by default so that you can boot to the previous kernel if the latest kernel has issues. After doing so, reboot to ensure nothing has gone wrong. Now, try sudo apt upgrade again, which should hopefully install the latest kernel and generate its initrd file. Reboot to the newly installed kernel and try sudo apt autoremove to remove any remaining pacakges as @[email protected] suggested
